I have installed the Winamp Equalizer app and changed the eq settings and they now sound more like traditional earphones because I boosted the high end.
Also, they saved my life a few weeks ago. I was fishing in a small creek in the bush and a tree fell. I had to jump out of the way. It was a eucalyptus tree about 4 feet across and 100 feet tall. If I hadn't heard it (had I been wearing traditional in-ear earphones) they would have been carrying me out of there in a bucket.
For future reference, and to keep you out of jail, always ask for consent before physical contact. Asking may seem awkward, or counterintuitive, but it removes doubt. Also, 'no' means 'no', and no reason or explanation is necessary.
